Addition of Strings To add, or “concatenate,”
two strings, just place a + sign between them.
Example:
LET A$ = “NOW”
LET B$ = “IS”
LET C$ = A$ +“
C$ = “NOW IS”
Addition can be used to input answers from the
keyboard longer than one character.
Example:
10 LET A$ = INKEY$
12 IF A$ = “" THEN GOTO 10
15 PRINT A$;
20 IF INKEY$O‘“" THEN GOTO 20

"+ BS

Jim March, pas

President of EBZUG, begins a regular
programming in Sinclair Basic.

AND BASIC Function (shift-“A”, code=218). AND
in T/S 1000 BASIC works differently than AND in
other BASICs.
A AND B, where A and B are numeric expres-
sions, returns A if B ¥ 0, or 0 if B = 0.
A$ AND B,where A$ is a string expression and Bis
a numeric expression, equals A$ if B #0, or “” ifB
=0.
The AND function allows you to do some very
compact coding.
Example:
5 SLOW
10 PRINT “USE THE 1-8 KEYS TO MOVE
THE”,“DOT IN THE DIRECTION SHOWN
BY",“THE GRAPHICS CHARACTERS”.
20 LET X=0
30 LET Y=0
40 PLOT X,Y
50 LET K$=INKEY$
60 IF K$O“" THEN GOTO 80
65 UNPLOT X,Y
70 GOTO 40
80 IF K$ <1" OR K$ >"8”" THEN GOTO 65
100 LET X=X+(1 AND (X<63 AND (K$="2"
OR K$="3”" OR K$="8")))-(1. AND (X>0 AND
(K$="1" OR K$="4" OR K$="5")))
110 LET Y=¥+(1 AND (Y<43 AND (K$="1"0R
K$="2" OR K$="7")))-(1 AND (Y>O AND
(K$="3" or K$="4" OR K$="6")))

the same as the line being copied.
Consider the line:

10 PRINT AT 6,15;°R®
The R in the above line can be
typed in with the cursor in either
the L mode or in the graphics G
mode. If you are as innocent as I
was you would probably type in the
R usint the L cursor mode. If R is
made into a user defined graphic
character (see Chapter 18 of the
2068 User Manual) somewhere in the
program, you can have trouble. If
R has been entered using the L
cursor mode, the R will print out
as R when the program is RON, but
this might not be what is wanted.
If R has been entered using the G
mode, the user defined graphic will
be printed out. The graphic symbol
will appear in place of R when the
program is brought back on to the
screen after it has once been run.
The lesson to learn is that if you
are typing in a program for the
2068 you must study the program to
determine if letters "A" to °0"
should be typed in the L mode or in
the G mode.

A second source of trouble occurs
when typing in the graphic symbols
found on the number keys 1 to 8
using the G cursor mode. If you
are a little hazy about how to type
these graphic symbols, you are apt
to get into the INVERSE VIDEO mode
part of the time. This won't keep
you from making the string of
graphics from looking exactly the
way you want it to look, but the
running of the program may be
stopped by an error signal. In py
particular case the error signal °R
- Invalid color® came up further on
the the program. This was puzzling
since color did not seem involved.
I had much trouble finding the
fault. Keep in mind that if you
get into the inversev video mode,
the cursor mode symbol will not
change to indicate it.

This program is @ fun and easy to use tool. It’s
possibilities, are quite extensive, and range from a sisple
sketch pad to- complete GRAFIC DESIONS, as wel) as VIDEO
DISPLAYS and so on.

There are various modes, (which will be explained in detail)
these include. Draw, TITLES, TEXT entry, DISPLAYS of TEXT or
“PICTURES”, saving & loading of gratic "files" setting PRINTER
and 80 on.

One of the important features, are the 3 STORE/RECALL pages.
These hold in memory, complete screens (colour H/R grafice
TEXT, TITLES, etc, and can be used for any purpose, including
ANIMATION or EDITING.

Following, are operating instructions for the various modes.

1-DRAW.. You can either use the JOYSTICK, or KEYS 1-8 (1-4
are for diagonal moves). To wipe out (erase), hold down the
firing button on the joystick, or prece key 0. If you use the
keys, then you wil] have to press key 9 in order to return to
normal drawing. The various sub aodes and their keys, are
displayed on the screcn at all] times.

Before the drawing is actually activated, (or at any tise
you wish), the colour options will be displayed. These will
always follow in the same order of input, PAPER bright or
normal, PAPER colour, FRAME, BRUSH, PEN, TITLES, CHARACTERS.

- BRUSH, is triple high resolution plotting, and therefore
is slower then PEN.

C-chrctr.. you will be prompted for an input of any keyboard
character including the grafice. Note.. do not enter more then
28 at one time, as screcn may automatically scroll upwords.
Chrctre will be printed on the line of your last drawing
position. Note.. FLASH applies only to these characters, and
is turned on and of with key F.

E-erase.. will erase the entire screen (leaving the frame),
and retaining all previous positions and colours or sub modes.

O-over will print or draw over without erasing, N-normal
cancels O-over. M-menu exits the DRAW mode.

S-store.. You wil] be prompted for the page number (1-3) and
the picture and frame wil] be stored in that page. This allows
you for eg, to start a drawing in certain colours, store it,
then experiment for a@ while, either cont storing, or recall
the original and go on. Therefore, it is advisable, before any
changes, to store the existing screen.

R-recal).. will of course recall any of the above mentioned
pictures.

T-TITLE.. Titles will also be printed on last drawing line,
however since these are of variable heights and widths, care
should be taken when specifying their dimensions, as they
erase everything in their path.

The TITLE pode can also be accessed seperately (MENU item
3), placed in storage and later recalled in DRAW mode before
FRAMING or drawing over.

I-ink will return to the above mentioned colour prompts.
Note.. We have included the “CHAMELEON” colour, which allows
the PEN, BRUSH, TITLE, chrctr, etc to adopt the colour of its
nearest plotting positions.

2-CIRCLE.. after entering the diametor, the computer will
automatically, draw a circle to the right of the last PLOTTING
position, (unless your specified size is too large for that
area)

ture left. Y-move picture rig
Tithe tees wil] scroll the picture sideways in the above
directions. Assuming. you have a drawing, and would like to
erase the right side, every time you press X, the picture will
wove to the right, therefore erasing that side, and bringing
the left side 1 step closer to the center. .

NOTE.. all af the above mentioned "subsodes” and features
can be used individually or in any combination. Please
experiment & “play” for a while, before attempting to recreate
the "MONA LISA". Ag you can see from the examples in the
program, the possibilities for creating "GARBAGE" are also
quite extensive.

MENU item 2-ENTER TEXT.

This mode is used for creating DISPLAYS (including TITLES),
for VIDEO, (credits, advertising etc).

The regular text is automatically “PROCESSED” (WORD
WRAPAROUND) etc. TITLES are entered at the same time, the
difference being as follows.

l- Enter an aeterik (symbl shift 8B). 2= now enter your
TITLE, (max 29 characters long). 3- Enter another asterik. The
asterike at the beginning and end of the titles, tell the
computer (upon DISPLAY), that the text contained between them,
should be enlarged and displayed in a seperate line and
perhaps cclour. To create a “proper” dieplay, enter text and
TITLES seperately.

When entering the TEXT (since the comaputer is in input, say
we Burgest.. that you onter every paragraph seperately. The
“PILE” can hold eproximately 1100 characters including the
ones used for TITLES. All files are automatically eaved and
loaded together with the 3 "PICTURE pages". Between entries of
TEXT or TITLES, you can at any time, start from scratch or
continue the TEXT in semory, which can be optionally displayed
before new input. Note.. TEXT and TITLES can not be EDITED
after entered, therefore Take care and do all your planning
and editing while in input (" ").

REMINDER- every seperate input will be treated as a new prerp

MENU item 6- DISPLAY/PRINT.

Thies of course will bring us to “the moment of trouth".
Pollowing will be 4 SUB MENU items.

1-VIEW (animate)- will display the 3 “PICTURES” every time
you hit the key for that page (0 will exit that SUB aode).
This can be affectively used for animation, and recorded on a
VCR, as there are no prompts or any information displayed on
the screen.

2-DISPLAY TEXT/TITLES- will do the same for the TEXT/TITLES
and will automatically scroll up and repeat, until any key is
preesed.

3- COPY pictures to printer- Will automatically printout the
3 pages, (TIMEX or CENTRONICS type DOT MATRIX printer.

4-TEXT/TITLES hard copy- will give you a printout to the
above mentioned printers, but including LETTER QUALITY
centronics interfaced printers.

S- will return you to the sain MENU.

MENU item 4- SET PRINTER .. you have to pase through this
gwode if you are using a CENTRONICS INTERFACE type PRINTER.
This progras includes a MC driver routine for aost popular
CENTRINICS printers.

MENU item 5- SAVE/LOAD- enter name of file (mark cassette
label if you are saving).

This ends these instructions. As usual, this programs is bug
free, PLEASE TAKE YOUR TIME in discovering its uses.
